Here is a link to the cooling system part of the fsm. If you change the thermostats out make sure you use oem not the $5 specials from autozone or similar place. Go to Nissan and buy them across the parts counter. I’ve paid as much as $45 for an oem vw thermostat before, just don’t cheap out on such an important part. If the thermostat fails open your vehicle never gets to proper operating temperature even in the summer. If it fails closed your engine overheats. I am really curious as to whether a new thermostat (s) solve this little to no heat problem. Please report back with work done and the results good or bad.

Thanks for the link! Weird thing is that I don't see a second thermostat in that document.. just one on the inlet side
Today I spent some time de-airing the cooling system and also observing operation of the radiator fans. I had the car running for at least half an hour, did not observe any air bubbles, also did not see either of the fans kick in at any time, with engine temp holding steady. I would have expected once the thermostat opens for one or both the fans kick in. I find this a bit strange
I did also observe that, as mentioned by the fellow Canadian above, once the system is put on any "defrost" setting will enable both fans to kick in and stay on, I suspect this to have been the culprit on the very cold day when I almost froze to death. The only way to turn off the fans is to cycle AC on then back off. This is good to know and obviously a design flaw
I just ordered a OBD2 dongle, next step is going to be observing coolant temperature for the next few weeks to get a gauge of what's going on. I will keep this thread posted
